Description

Patented Oct. 19, 1926.
VACLAV HEJ'MA, F BRNO, CZECHOSLOVAKIA.
HEATING APPARATUS.
Application filed September 13, 1924, Serial No. 787,514, and in Czechoslovakia January 26, 1924.
The subject matter of the present invention consists of a heating device which is suitable not only for chamber stoves and other heating installations, but also for boiler furnaces and the like.
In the drawings there is shown in Figure 1 a diagramn'iatie view of a plant, provided with the means according to the invention, for heating dwelling rooms. Figure 2 is across section of the oven taken on the line Tit-11, Fig. 1; Figures 3 and 41 are a plan and vertical cross section on a larger scale of the grate, and Figure 5 is a detail there of. Figures 6 and 7 show the device as used for boiler furnaces.
The device according to the present invention makes use of the fact that, for the complete combustion of the gases of com bustion and of the smoke, itis necessary to locally separate the firing of the fuel and the combustion of the lire zone and above the firing gases to allow a throttled air duct to open into the firing chamber.
Consequently a stove for a room will in.
accordance with the present invention, be made as follows:
In the fireproof-lining 2, of the cylindrical combustion chamber 1 several nozzle shaped openings 8 are arranged at an acute angle to its jacket surface and inclined somewhat horizontally, said openings being in communication with the external atmosphere by means of vertical ducts 5 and also with a chamber 7 arranged below the ash pan 6. In the front wall of the stove there is provided the filling chamber 10 with a double door 8, 9 the inclined bottom plate 11 of said chamber being fashioned at its inner edge in the form of a grate. Below this there is also a chamber 13, adapted to be closed by a door 12, through which access can be had to the surface of the grate.
The grate 1 consists preferably of several concentric crowns (Figures 3 and 1) with radial projections and held together by means of diametric arms and rests upon an uneven step bearing 14:, so that it can be turned in both directions by means of the handle 15 with simultaneous raising and lowering.
To the top of the combustion chamber 1 there is connected a cylindrical radiating body 16, provided with external heating ribs, from which the products of combustion pass on to the chimney through a number of flatchambers 17 (Figures 1 and 5) formed with distributing partitions 18 and which are accommodated in different rooms or spaces.
An air heating plant may advantageously be combined with this stove. For this purpose the radiating body 16 is surrounded by a sheet iron jacket; the intermediate chamber 19 formed in this way is inserted in the piping 20, with which heating chambers 21 are connected. The part of the piping 20, guided through the chamber 7 filled with water, is fashioned as a perforated coil so that the circulating heating air carries steam along with it and the coil 2O also serves to heat the aid in the chamber 7 so that partly preheated air is fed to the ducts 5. All the ducts and pipes are preferably provided with slides, dampers or similar closing organs.
The device according to the invention can be adapted to boiler furnaces by inserting, at the two longitudinal sides, flat hollow members 22 the downwardly and inwardly bent lower edges of which contain openings 23 for the air feed ducts 24.
To fit these members it is only necessary to remove a few grate bars.
What I claim and desire to secure by Letters Patent of the United States is 1. Heating apparatus comprising a substantially circular combustion chamber, means for supporting a pile of fuel in such chamber, and means for supplying additional air to the space above such pile comprising vertical air passages in the wall of the chamber, a series of air nozzles penetrating the wall of the chamber and inclined downward and tangential to a cone spaced from the fire pot.
2. Heating apparatus comprising a substantially cylindrical combustion chamber, a substantially circular lire grate for supporting a fuel pile in the lower part of said chamber, air admission nozzles penetrating the side walls of the said chamber above said pile and inclined downwardly and tangential to a cone spaced from the fire pot, and vertical passages in the said side walls for supplying air to the said nozzles.
Signed at Prague, Czechoslovakia, this 23rd day of August, 1924.
